背景技术Background Art
可视鼻胃肠管镜是一种用于检查鼻腔、咽喉、食管、胃和十二指肠等消化道部位的内窥镜。它由一根柔软的管状探头和相关的光源、摄像设备等组成。通过引导探头进入人体内部，医生可以实时观察消化道的情况，以诊断疾病或进行治疗。The visual naso-gastrointestinal endoscope is an endoscope used to examine the nasal cavity, throat, esophagus, stomach, duodenum and other parts of the digestive tract. It consists of a soft tubular probe and related light sources, camera equipment, etc. By guiding the probe into the human body, doctors can observe the digestive tract in real time to diagnose diseases or provide treatment.
其中中国专利(CN219208175 U)公开了基于一种可视鼻胃肠管镜,包括：第一管道；第二管道，其以能够拆卸的方式安装于第一管道内，其左端能够伸入第一管道的左端并通过限位机构限位，其左端面上设有摄像头、照明灯和喷头；第二管道内设有成像照明通道和水气通道，喷头与摄像头对应设置；第一管道的左端和第二管道的左端均为弯曲部，第二管道内设有角度调节装置；主机，成像照明通道用于将成像照明通道和摄像头与主机连接，且主机上设有显示屏；以及水气系统，水气通道用于将喷头和水气系统连接。采用本实用新型的可视鼻胃肠管镜，第一管道在可视引导下插入小肠内，安全可靠；通过喷头的作用，既能给肠胃送水润滑，又能给肠胃送气，便于第一管道的插入。Among them, the Chinese patent (CN219208175 U) discloses a visual nasogastric tube endoscope, including: a first pipe; a second pipe, which is installed in the first pipe in a detachable manner, and its left end can extend into the left end of the first pipe and be limited by a limiting mechanism, and a camera, a lighting lamp and a nozzle are arranged on its left end surface; an imaging lighting channel and a water-gas channel are arranged in the second pipe, and the nozzle is arranged corresponding to the camera; the left end of the first pipe and the left end of the second pipe are both curved parts, and an angle adjustment device is arranged in the second pipe; a host, the imaging lighting channel is used to connect the imaging lighting channel and the camera to the host, and a display screen is arranged on the host; and a water-gas system, and the water-gas channel is used to connect the nozzle and the water-gas system. With the visual nasogastric tube endoscope of the utility model, the first pipe is inserted into the small intestine under visual guidance, which is safe and reliable; through the action of the nozzle, water can be supplied to the stomach and intestines for lubrication, and air can be supplied to the stomach and intestines, which is convenient for the insertion of the first pipe.
上述对比文件中的可视鼻胃肠管镜存在的不足：在摄像头被污染物遮挡时，按下水气按钮，虽然可以通过水气系统给喷头送水或送气，冲洗摄像头，冲洗后摄像头表面可能会残留粘液或水，易在摄像头保护罩表面形成挂留水滴，从而摄像头的视线不清晰，影响医生对病情的判断；The visual nasogastric tube endoscope in the above-mentioned comparative document has the following deficiencies: when the camera is blocked by contaminants, pressing the water and gas button can supply water or gas to the nozzle through the water and gas system to flush the camera. However, mucus or water may remain on the surface of the camera after flushing, and it is easy to form hanging water droplets on the surface of the camera protective cover, so that the camera's line of sight is not clear, affecting the doctor's judgment of the condition;
为此我们设计出一种可视鼻胃肠管镜。For this purpose, we designed a visual naso-gastrointestinal tube endoscope.
